PRIMER BULB
The PRIMER BULB removes air from
the carburetor and fuel lines and fills
them with fuel. This allows you to start
the engine with fewer pulls on the
starter rope. Activate primer bulb by
pressing it and allowing it to return to
its original position.
OPERATING TIPS
• While vacuuming or blowing debris,
hold the unit with the muffler side fac-
ing away from your body and clothes
(see OPERATING POSITION below).
• To reduce the risk of hearing loss
associated with sound level(s), hear-
ing protection is required.
• To reduce the risk of injury associated
with contacting rotating parts, stop the
engine before installing or removing
attachments. Do not operate without
guard(s) in place.
• Operate power equipment only at rea-
sonable hours-not early in the morn-
ing or late at night when people might
be disturbed. Comply with times listed
in local ordinances. Usual recommen-
dations are 9:00 a.m. to 5:00 p.m.,
Monday though Saturday.
• To reduce noise levels, limit the num-
ber of pieces of equipment used at
any one time.
• To reduce noise levels, operate pow-
er blowers at the lowest possible
throttle speed to do the job.
• Use rakes and brooms to loosen
debris before blowing.
• In dusty conditions, slightly dampen
surfaces or use a mister attachment
when water is available.
• Conserve water by using power blow-
ers instead of hoses for many lawn
and garden applications, including
areas such as gutters, screens, patios,
grills, porches, and gardens.
• Watch out for children, pets, open
windows, or freshly washed cars.
Blow debris away safely.
• Use the full blower nozzle extension
so the air stream can work close to
the ground.
• After using blowers and other equip-
ment, CLEAN UP! Dispose of debris
in trash receptacles.
START LEVER
The START LEVER helps to supply fuel
to the engine to aid in starting. Activate
the starting system by moving the start
lever to the START position. DO NOT
squeeze the throttle trigger until the
engine has started and runs. After the
engine starts, allow the engine to
warm-up 10-15 seconds, then fully
squeeze the throttle trigger to deacti-
vate the starting system (start lever re-
turns to RUN position).

BEFORE STARTING ENGINE
_IL WARNING: Be sure to read tile
fuel information in the safety rules
before you begin. If you do not
understand the safety rules, do not
attempt to fuel your unit. Call
1-800-235-5878.
FUELING ENGINE
_WARNING: Remove fuel cap
slowly when refueling.
This engine is certified to operate on un-
leaded gasoline. Before operation, gaso-
line must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil.
We recommend Craftsman brand syn-
thetic oil. Mix gasoline and oil at a ratio
of 40:1. A 40:1 ratio is obtained by mix-
ing 3.2 ounces of oil with 1 gallon of un-
leaded gasoline. Included with this blow-
er is a 3.2 ounce container of oil. Pour
the entire contents of this container into
1 gallon of gasoline to achieve the prop-
er fuel mixture. DO NOT USE automotive
oil or boat oil. These oils will cause en-
gine damage. When mixing fuel, follow
instructions printed on container. Once
oil is added to gasoline, shake container

momentarily to assure that the fuel is
thoroughly mixed. Always read and fol-
low the safety rules relating to fuel be-
fore fueling your unit.
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract mois-
ture which leads to separation and
formation of acids during storage.
Acidic gas can damage the fuel sys-
tem of an engine while in storage.
To avoid engine problems, empty the
fuel system before storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh
fuel next season. Never use engine or
carburetor cleaner products in the fuel
tank or permanent damage may occur.
Fuel stabilizer is an acceptable alter-
native in minimizing the formation of
fuel gum deposits during storage.
Craftsman brand oil is already blended
with fuel stabilizer. See the STORAGE
section for additional information.
